Oral anticoagulant therapy is widely used in different patients for the prevention and treatment of thromboembolic events: in atrial fibrillation, deep vein thrombosis/pulmonary embolism, acute coronary syndrome, in the early postoperative period after orthopedic surgery. Nowadays it is possible to use vitamin K antagonists (warfarin) as well as direct oral anticoagulants (DOAC): dabigatran, rivaroxaban, apixaban and edoxaban. The mai complication of any anticoagulant therapy is bleeding (gastrointestinal, intracranial, etc.), which seriously limits its usage. In this review the incidence of gastrointestinal bleeding (GIB) associated with oral anticoagulants intake was analyzed according to the results of both large randomized and postregistration trials. Furthermore, the effect of age on the risk of GIB development is discussed, and also aspects of the pathophysiology of gastrointestinal mucosa lesions in patients taking DOAC are considered.

Several direct oral anticoagulants have been developed to prevent cardiogenic thrombosis in patients with atrial fibrillation, on the other hand, have the complication of bleeding. Since clinical course after bleeding with direct oral anticoagulant remains unclear, the present retrospective cohort study was to clarify the course after hemorrhage among patients receiving direct oral anticoagulants. Among all 2005 patients prescribed dabigatran, rivaroxaban, apixaban, or edoxaban between April 2011 and June 2017, subjects comprised 96 patients with non-valvular atrial fibrillation who experienced relevant bleeding during direct oral anticoagulant therapy (Bleeding Academic Research Consortium type 2 or above). The clinical course after hemorrhage was reviewed to examine whether rebleeding or thrombotic events occurred up to the end of December 2019. Gastrointestinal bleeding was the most frequent cause of initial bleeding (57 patients, 59%). Rebleeding occurred in 11 patients (4.5%/year), with gastrointestinal bleeding in 10 and subarachnoid hemorrhage in 1. All rebleeding occurred in patients who resumed anticoagulation therapy. Another significant factor related with rebleeding included past history of gastrointestinal bleeding. On the other hand, major adverse cardiac and cerebrovascular events occurred in 6 patients older than 75 years old or more (2.5%/year), with systemic thrombosis in 4 and cardiac death in 2. All 4 patients with systemic thrombosis withheld anticoagulants after index bleeding, although only 10 patients withheld anticoagulation therapy. Rebleeding should be taken care of when anticoagulants are resumed after bleeding, particularly among patients who initially experienced gastrointestinal bleeding. Systemic thrombosis occurred at a high rate when anticoagulant therapy was withheld after bleeding.

Background : Major bleeding is a life-threatening condition and a medical emergency with high mortality risk. It is often the complication of anticoagulant’s intake. Anticoagulants are commonly used for the prevention and the treatment of thrombotic events. The standard therapy with vitamin K antagonist (warfarin) has been frequently replaced by direct oral anticoagulants (DOACs). The latter agents (rivaroxaban, apixaban, edoxaban, dabigatran, betrixaban) showed a better efficacy and safety compared to standard warfarin treatment and they are recommended for the reduction of ischemic stroke. Literature data reported a high risk of gastrointestinal bleeding with DOACs, in particular with dabigatran and rivaroxaban. In case of life-threatening gastrointestinal bleeding, these patients could benefit from the use of reversal agents. Methods: We performed an electronic search on PUBMED of the literature concerning reversal agents for DOACs and gastrointestinal bleeding in the Emergency Department from 2004 to 2020. AIM: This review summarizes the current evidences about three reversal agents idarucizumab, andexanet alfa and ciraparantag, and the use of the first two in the emergency setting in patients with an active major bleeding or who need urgent surgery to offer physicians indications for a better management approach in order to increase patient’s safety. Conclusion: Although these agents have been marketed for five years (idarucizumab) and two years (andexanet alfa) respectively, and despite guidelines considering antidotes as first-line agents in treating life-threatening hemorrhage when available, these antidotes seem to gain access very slowly in the clinical practice. Cost, logistical aspects and need for plasma level determination of DOAC for an accurate therapeutic use probably have an impact on this phenomenon.. An expert multidisciplinary bleeding team should be established so as to implement international guidelines based on local resources and organization.

Administration Routes

Heparin-based delivery systems have been explored to improve their therapeutic efficacy and to reduce toxicity for different administration routes. Regardless of the applied drug delivery system (DDS), the evaluation of anticoagulant performance is instrumental for the development of a suitable DDS. The understanding of the range of anticoagulant assays, together with their key applications and limitations, is essential both within the context of scientific research and for clinical usage. This review provides an overview of the current anticoagulant therapy and discusses the advantages and limitations of currently available anticoagulant assays. We also discuss studies involving low-molecular-weight heparin (LMWH)-based nanocarriers with emphasis on their anticoagulation performance. Conventional anticoagulants have been used for decades for the treatment of many diseases. Direct oral anticoagulants have overcome some limitations of heparins and vitamin K antagonists. However, the lack of an accurate laboratory assessment, as well as the lack of a factor “xaban” (Xa) inhibitor reversal agent, remains a major problem associated with these anticoagulants. LMWHs represent anticoagulant agents with noteworthy efficacy and safety, and they have been explored to improve their outcomes with various nanocarriers through several administration routes. The main problems related to LMWHs have been surmounted, and improved efficiency may be achieved through the use of DDSs.

Retrospective Cohort Studies

Objective: To evaluate current clinical evidence for management of oral anticoagulation therapy after gastrointestinal bleeding (GIB) with an emphasis on whether to, when to, and how to resume an anticoagulation therapy. Data Sources: Relevant articles from MEDLINE, Cochrane Library, and EMBASE databases were identified from 1946 through May 20, 2017, using the keywords: gastrointestinal hemorrhage or gastrointestinal bleeding and antithrombotic therapy or anticoagulation therapy or warfarin or dabigatran or rivaroxaban or apixaban or edoxaban.Study Selection and Data Extraction: All English-language studies assessing management of oral anticoagulation therapy after GIB were evaluated. Data Synthesis: A total of 9 studies were identified. Four retrospective cohort studies showed that resuming anticoagulation therapy was associated with significantly lower rate of thromboembolism (TE) in the general population. Meta-analyses and prospective cohort studies also supported this finding. Two retrospective cohort studies indicated an increase in GIB when anticoagulation reinitiation occurred in less than 7 days without a decrease in TE. Resuming therapy between 7 and 15 days did not demonstrate a significant increase in GIB or TE. A large retrospective study showed that apixaban was associated with the significantly lowest risk of GIB compared with both rivaroxaban and dabigatran. Conclusion: Anticoagulation therapy resumption is recommended, with resumption being considered between 7 and 14 days following GIB regardless of the therapy chosen. Data for warfarin management after GIB should be applied with caution to direct oral anticoagulants (DOACs) because of the quicker onset and experimental nature of reversal agents. Apixaban may be a preferred option when restarting a DOAC therapy.

Рассматривается современное состояние вопроса выбора антикоагулянтной терапии при фибрилляции предсердий (ФП) у онкологических больных. Отмечается, что сложность выбора антикоагулянта при злокачественных новообразованиях (ЗНО) определяется такими факторами, как коморбидные сердечно-сосудистые заболевания, нарушения функции печени и почек, метаболические дисфункции, свойственные, прежде всего, пациентам старшей возрастной группы. Приводятся актуальные данные по оценке риска геморрагических и тромбоэмболических осложнений ФП при ЗНО в аспекте возраста. Обсуждаются возможные причины увеличения риска развития ФП во время и после лечения ЗНО, в том числе и в связи с возраст-ассоциированностью этих патологий. Рассмотрены вопросы выбора антикоагулянтов у пациентов, находящихся на активной противоопухолевой терапии, особенно на препаратах из группы прямых оральных антикоагулянтов (ПОАК). Согласно данным обсервационных исследований, именно ПОАК являются перспективным, относительно безопасным и эффективным выбором для онкологических пациентов с ФП, в связи с чем их применение должно активно изучаться в рандомизированных клинических исследованиях с учетом фактора возраста. Подчеркивается, что подбор схемы антикоагулянтной терапии у пациентов с ФП и ЗНО требует междисциплинарного участия кардиологов и онкологов, а часто и гериатров, чтобы индивидуализировать лечение и предложить наиболее эффективную терапию. The current issue of the choice of anticoagulant therapy of atrial fibrillation (AF) in cancer patients is considered. It is noted that the difficulty of choosing an anticoagulant in malignancies is largely determined by age-related factors, such as comorbid cardiovascular diseases, liver and kidney dysfunction, metabolic disorders common for in elderly patients. Current data on the risk assessment of hemorrhagic and thromboembolic complications of AF in cancer patients in the aspect of age presented. During and after cancer treatment, the risk of developing AF can increase, also in connection with the age-associated pathology. Possible reasons of it are discussed. The choice of different anticoagulants groups in patients treated with anticancer therapy, including direct oral anticoagulants (DOAC) is considered. According to available data from observational studies, it is the DOAC that is a promising, relatively safe and effective choice for cancer patients with AF, and therefore their use should be actively studied in randomized trials, considering the factor of age. It is particularly noted that solving this problem requires the interdisciplinary involvement of cardiologists, oncologists, and sometimes, geriatrics, to individualize treatment for each case and to offer the most effective therapy.

This review focuses on issues of anticoagulant therapy in patients with atrial fibrillation (AF) associated with chronic kidney disease (CKD). Such patients are at high risk of stroke whereas the choice of an anticoagulant is difficult. A wealth of information about a negative effect of warfarin on the kidney function has accumulated. A need for an alternative therapy to warfarin for patients with stage 3-4 CKD has become imminent. In this regard, rivaroxaban seems to be an appropriate replacement for warfarin in such patients. In randomized, controlled studies that evaluated the efficacy of direct oral anticoagulants in comparison with warfarin, the efficacy and safety profile of a “kidney” dose in moderate disorders of kidney function has been studied only for rivaroxaban. Moreover, both randomized, controlled studies and studies performed in the conditions of clinical practice, have demonstrated a more favorable effect of rivaroxaban on kidney function compared to warfarin. Patients with AF associated with CKD require a comprehensive protection, which, according to results of clinical studies, may be provided by rivaroxaban.
